A few weeks ago [Jacob Merz] sent me an email about his sensory expansion project, which allows the wearer to “hear” infrared light by mapping it to specific tones. Although a rough prototype, [Jacob's] device reflects a larger realm of technological possibilities: the development of a type of “peripheral” for the human body.
You’re going to want to listen to [David Eagleman's] TEDx Alamo talk particularly around 10 minutes in, where he talks about the sonic glasses. [Eagleman] claims that the human brain, if given a consistent input that corresponds to the real world, can decipher the signal into usable information. The sonic glasses, which provide a type of sonar to the blind wearer, eventually just…work. Your brain can “learn” its own drivers for input devices.
